FIELD: process engineering. ^ SUBSTANCE: invention relates to techniques of producing soft contact lenses. Proposed method comprises dissolving coloring agent in hydrophilic monomer represented by N-vinylpyridone, copolymerising obtained solution with hydrophobic monomer, i.e. methyl methacrylate in the presence of divinyl crosslinking agent. It further on comprises processing of obtained polymer mix and producing contact lenses. Proposed method differs from known ones in that it uses anthraquinone dye as a dye and in that monomer copolymerisation is performed under effect of ionising radiation. ^ EFFECT: simplified technology, improved physical-chemical properties on lenses. ^ 4 cl, 1 tbl, 9 ex |
